KARN United States Patent O 3,274,038 DllSlPlENlNG DEVICE Andrew B. Kam, 420 E. 86th St., New York, NSY. Filed lian. 14, 1963, Ser. No. 251,385 18 Claims. (Cl. 15d-247') The present invention relates to tape dispensing devices, and, more particularly, to novel and improved methods and apparatus for dispensing tape having a plurality of separable layers, one of which is waste, and for applying a release-type pressure-sensitive `adhesive from a transfer tape to a surface to be coated.

Various techniques `and devices have been developed :for dispensing or applying adhesive and the like, such as that disclosed Vin Patent No. 2,845,041, granted to A. B. Karn lon July 29, 1958, wherein an adhesive applicator device applies an adhesive releasably affixed to a backing tape to a surface. In the various embodiments disclosed in that patent, for example, the tape, commonly referred to as a transfer tape, is forced against a surface by a rotatable feed roller. The rotation of the feed roller either directly or through a mechanical chain drive, feeds the waste tape backing lor body onto a take-up spool, or into a storage chamber, or outwardly of the dispenser housing.

In each of the embodiments of Patent No. 2,845,041 and other known devices, the operation of the devices hinges upon the proper functioning of a plurality of moving elements, some of which are driven by various types of drive mechanisms, which render the device more costly and more complicated in manufacture, assembly, and use than is acceptable for general use as an over-the-counter item.

In accordance with the novel and improved methods and apparatus of the invention, the dispensing and application 'of transfer tape and the like is accomplished by apparatus employing no moving parts, and having a very simplied housing including a fixed mandrel, a fixed tape engaging means, and a fixed guide means, which is susceptible of being readily manufactured, assembled with and 4used for dispensing tape havin-g a plurality of separable layers from a roll. In one embodiment, adhesive may 'be applied to an appropriate surface by merely pushing the applicator across the surface so that the adhesive is stripped from the transfer tape liner to which it is relatively lightly bonded and transferred to the surface to be coated, the waste liner being automatically fed through a guide channel for disposal and separation from adjacent layers of unused tape. In other embodiments of the invention, `a tape having adhesive on one `or both sides of a coated paper liner, which may be separated from a waste liner, may be used in the dispenser, and either applied directly to a surface or fed from the dispenser for later application to such a surface. In all of the embodiments, the waste liner is separated from the adhesive or tape and guided in the dispenser to an appropriate location for disposal.

For a more complete understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying figures of the drawings, in which:

In FIG. 1, ya roll of transfer tape 10, having a con ventional core 11, is mounted on a hollow mandrel 12, formed integrally with or mounted on a generally circular housing 13, which may be formed, for example, of any suitable conventional plastic material. The roll of tape 10 and its core 11 are adapted to rotate about the mandrel 12 during withdrawal `of tape therefrom. The roll of tape 10 comprises a tape wound about the core 11 having at least tWo separable layers, including a waste liner 14 and an adhesive 15, mounted on and radially outward of the waste liner 14. The liner 14 may consist lof any suitable flexible material such as, for example, Holland cloth or glassine, with a suitable conventional release coating, if desired, separating the liner 14 from the adhesive 15, which may be a suitable ever-tacky gum or a web-reinforced ever-tacky gum, the materials of the liner 14 and the adhesive 15 `bein-g so chosen as to have only slight affinity.

The housing 13 is shown as being formed in two complimentary sections including a back plate 16 (FIG. 1) and a cover plate 17 (FIG. 2) with respective mating flanges 18 and 19.

A peripherally exposed tape engaging means or applicator 20 having a rounded outer surface extend slightly beyond the back plate 16 and the cover plate 17, when the housing 13 is assembled, is formed integrally with or otherwise suitably mounted on the back plate 16. The tape engaging means 20 is in the form of a hollow cylinder, similar to the mandrel 12, each being adapted to receive respective studs 21 and 22, which are formed integrally with or mounted on the cover plate 17.

A flange 18 extends peripherally along `a portion of the back plate 16 and then inwardly thereof in a generally circular manner with `a rounded outwardly hooked shaped extremity 24 forming a portion of a guide means 25. An additional fiange 26 is mounted peripherally on the back plate 16 and extends along and substantially parallel to that portion of the flange 18 leading `to the hooked shaped `member 24 to form a disposal chamber 27. One extremity of the flange 26 approaches, but is spaced from, the flange 18 to form an external opening to the disposal chamber 27. The other extremity 28 of .the flange 26 curves inwardly on the back plate 16 about the hooked shaped member 24, but in spaced-apart relation thereto, to form a channel or guide path leading into the disposal chamber 27, and constitutes a second element of the guide means 25.

A third element of the guide means 25 comprises an upstanding post or parting stud 29 spaced outwardly of a tangential projection from the maximum circumferential portion of -the roll of tape 10 to the rounded tape engaging means 20, and is `spaced apart from the hooked shaped member 24 and the flange portion 28 a distance sufcient to form therewith respective guide channels or paths.

The flange 19 on the cover plate 17 is formed in ltwo sections which overlie and mate with the peripheral portions of flanges 18 and 26 on the back plate 16, with an opening provided from the disposal chamber 27.

In assembly, the roll of tape is placed about the mandrel 12 and a lead portion of the tape is withdrawn and passed through the guide means 25, in a path between the post 29 and the hooked shaped member 24 and the post 29 and the extension 28, around the tape engaging means 20 and with its liner 14 in overlying relation and in frictional engagement with a circumferential portion of the roll 10. The liner 14 continues around the roll 1t) and .passes therefrom in a path adjacent a portion of the tape extending from the roll 10 to the guide means 25, and thence on a path through the guide means 25 between the post 29 and the hooked shaped member 24, and then between the extension 28 and the hooked shaped member 24 into the disposal chamber 27 and outwardly therefrom. That portion of the tape leading beyond the tape engaging means 20, on original assembly, preferably consists of the waste liner 14 without any adhesive 15.

In use, the tape engaging means 20 and the adjoining tape is placed adjacent a surface 34B, which is to be coated. External pressure is either manually or mechanically placed upon the housing 13 to force the tape engaging means 20 against the surface 30 and push the entire housing in the direction of the arrow along the surface to be coated. The pressure exerted by the housing 13 and its xed tape engaging means 20 upon the tape causes the release-type pressure-sensitive adhesive to coat the surface 3l). The waste liner 14 is then separated from the transferred adhesive 15 and is drawn over the roll 10 by the driving relation established through the closed belt surrounding both the roll 10 yand the rounded tape engaging means 20. This driving relation causes a controlled rotation of the roll 10 about the mandrel 12, feeding new tape, including the adhesive 15, through the guide means 25, where it is separated from the previously exhausted waste liner 14 by being drawn in a path toward the tape engaging means from the post 29 at an angle to its path from the circumference of the roll 10 to the post 29. The flange 18 serves to guide the leading portion of the waste liner 14 into the guide means 25 during original assembly, in the event that the leading portion of waste liner 14 is not pressed into full contact with the circumferential portion of roll 1t) by the operator. The parting `stud or post 29 provides a xed axis, in denite spatial relationship to the other elements 24 and 28 of the guide means 25, about which the tape and the overlying waste liner may be separated and induced into separate paths. The elements 24 and 28 of the guide means 25 provide a relatively gently curved channel through which the exhausted waste liner 14 is pushed by means of the driving relation of the closed belt of tape.

The member 24 of the guide means 2.5 also provides thrust upon the waste liner 14, thereby maintaining it in frictional contact with the underlying section of tape as the waste liner is pushed through the guide means 25, and when the leading .portion of the waste liner 14 is torn off, after it has been discharged from the disposal chamber 27. Thrust is also provided by the ange 26 and its curved extension 28, as they maintain the waste liner 14 in a curved path.

A feature of this embodiment, in which the parting stud is located outwardly from a line tangential to the maximum outer circumference of the ltape roll 10 and the rounded tape engaging means and applicator 20, is that it is self-threading-Athat is, during original assembly, once theleading portion of the waste liner 14, which emanates from the applicator 20, has been placed into frictional engagement with a circumferential portion of the roll 10, the waste liner 14 will, without further handling, be automatically guided through the guide means 25 and lead out of the dispenser, as it is used to dispense adhesive.

In some cases, the chamber 27 may be normally closed to store the exhausted waste liner 14 in any suitable manner. A conventional cutting edge may be formed on the extremity of the flange 26 to facilitate cutting off portions of exhausted waste liner.

When the dispensing device is being withdrawn from the surface 30, thereby breaking the adhesive 15, it is desirable when the adhesive is of a type having appreciable tensile strength to brake the withdrawal of tape from the roll 1t). In the embodiment 'of FIGS. 4 and 5, the housing 13 has a side wall 36 including therein a flexible braking ange 37, which may be manually pressed inwardly of the housing 13 against the exhausted waste liner 35 and a new section of a transfer tape 38, and a brake 39 mounted on or formed integrally with the housing 13 at a point intermediate a roll of tape 40 and a guide means 41, but preferably outwardly of a tangential projection therebetween. Pressure of the braking flange 37 against the tape 38 and the brake plate 39 brakes the wi-thdrawal of tape from Ithe roll 40. The `structural details of the embodiment of FIGS. 4 and 5 may be otherwise similar to that of FIG. l, in that there is a closed belt driving relation involving the r-oll of tape 40 and a xed tape engaging means or applicator 42.

FIG. 4 also illustrates a variation of the guide means whereby the waste liner is iangularly displaced from the plane which contains the tape roll and tape and is conducted externally of the dispenser through an opening 45 in the back .plate 43. This displacement may be lachieve by appropriately canting the curved element 44.

In FIG. 6, the flexible braking flange 37 has an enlarged extremity 46 adapted to force the tape 38 into a hollow 47 in a brake plate 48.

In the embodiment of FIG. 7, the braking action is accomplished by manual insertion of a finger through an aperture in the housing 51 of the dispenser against the tape 52 as it passes over a brake post 53 formed in the housing.

When using rolls of tape where there is a large differential between the maximum diameter of the tape roll I'and the diameter of the core when the tape is exhausted, the guiding function of a ange 64 (FIG. 8) may be augmented by positioning a` suitably curved guide flange 61 on the housing of the dispenser at a point intermediate a roll of tape 62 and a guide means `63 outwardly of a tangential projection drawn from the maximum circumferential extent of the roll e2 to the guide means 63, thereby fixing the direction of movement or path of the tape from the roll 62 as it approaches the guide means 63 independently of the diameter of the roll of tape at any time during its use. It is noted that this function is also provided by the brake plates 39, 48, and 53 of FIGS. 4, 6 and 7.

In the embodiment of FIG. 9, a guide means 71, which functions similarly to the guide means of the other embodiments, is positioned on the housing at a point relative to a tape engaging or applicator means 72, whereby a roll of tape 73 is interposed in the path from the guide means 71 to the tape engaging means 72. This embodiment functions similarly to the other embodiments, with the exception that the tape 74 being withdrawn from the roll 73, after separation from the exhausted waste liner at the guide means, passes in overlying relation and in frictional engagement with the roll 73 for at least an additional circumferential extent. The purpose of positioning the guide means in this manner, close to the trailing edge of the dispenser, is to facilitate the passage of waste liner over the hand which holds the dispenser.

FIG. l0 illustrates an embodiment in which a rounded tape engaging means 91 comprises an element of the guide means 92, by incorporating the functions of the parting stud 29 (FIG. l) in addition to its tape applying function. This embodiment has the advantage of somewhat simplified construction. However, since the other elements 93 and 94 of the guide means 92 are located in close proximity of the tape engaging means 91, the operators view of the surface `95 Ito which the adhesive layer is affixed is somewhat obstructed.

Thus there has been provided, in accordance with the invention, novel and improved tape or adhesive dispensing methods and apparatus of a greatly simplified nature, employing no moving parts, which are susceptible of utilization in a wide variety of applications.

It will be obvious to those working in the art that the above-described embodiments and methods of use are meant to be merely exemplary, and that they are susceptible of modification and variation without departing from the spirit and scope of the invention. For example, the dispenser may be used with a saturated tissue reinforced type of transfer tape or a tape having adhesive on one or both sides of a coated paper liner, which is 4to be separated from an additional waste liner, the coated paper liner and adhesive being applied directly to a surface or merely withdrawn from the dispenser across the tape engaging means for later application to a surface. Also, in some instances it may be desirable to use a rotatable applicator or tape engaging means instead of a fixed applicator. Therefore, the invention is not deemed to be limited except as defined by the appended claims.
